## What it is
libloading is a Rust crate providing safe, cross-platform bindings around dynamic library loading primitives (dlopen/LoadLibrary). It lets programs load shared libraries at runtime and call their functions or access their symbols with compiler-enforced lifetime safety.

## Use cases
- load a shared library at runtime in Rust
- call functions from a .so or .dll dynamically
- build a plugin system with runtime-loaded modules
- wrap dlopen and LoadLibrary with a safe API
- get symbols from a dynamic library safely
- load native libraries for FFI at runtime

## When to choose
- you need to load shared libraries at runtime in Rust with memory safety
- you are building a plugin architecture that loads native modules
- you want a cross-platform alternative to calling dlopen/LoadLibrary directly

## When to avoid
- you only need compile-time linking to a C library (use a -sys crate instead)
- you need to hide all platform behavioral differences between dynamic loaders
- you need to load non-native plugins like WASM or interpreted scripts

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools
- domain: developer-tools, operating-systems, cross-platform
- platform: windows, rust, cross-platform
- tags: ffi, dynamic-library-loading, shared-libraries, dlopen, loadlibrary, plugin-system, linux, macos
